I have a 2021 expedition. Two days ago drove it everything seemed fine. Yesterday morning open a back door and it smells musty. Go to put my front passenger seat forwards and we notice water pouring from the back of the seat on both sides where the seat goes up and back. It was ice cold water too. A couple hours later I noticed the front seat is wet. Dealership can't find anything wrong and has no idea.

Check the sunroof. By front seat being we I figure you were talking about the seat, has to come from above. For the heck of it take a look around the bolts that anchor the seat. Check for rust around them. Did you buy it used or new from a dealer.

Sunroof has to be a prime suspect. Can the sunroof be open a tad without an alarm light?

Cooled seats? Perhaps condensation not running off/evaporating as designed? Seems like a good amount of liquid to be that though. Just a random guess if it's 100% not the sunroof and no obvious leaks anywhere else up high. I'm not too familiar with the 4th gen.
Could somebody not closed it tightly? Thats a heck of a lot of water Is the shade damp? Stick some paper towels around the sunroof, see if they get wet.

This right here.
The cooled seats to my experience use a fan only.

Well it doesn’t make sense why you have ice cold water there if they are fan only. And it’s only on the bottom part of the seat where the back and bottom cushions meet which is also weird. So obviously that water is coming from somewhere around the seat and the only possibly location would have to don with the cooled/heated function. I wonder if you had condensation built up and when you turn them on it pushes water out first?
I have had cooled seats in 10 different vehicles and have not that experience. What is confusing is the amount and having it on the cushion on the passenger seat. The temperature is strange as well.

100% the cooled seats use a fan device (Thermo-Electric Device) only. The same device is used for both heating and cooling of the seats. I suppose a defective TED, given the right circumstances, could produce condensation.
Is the fan device under the seat somehow staying on after the vehicle is off? I can see if the TED under the seat was running for like 24 hours straight it could ice up and produce condensation.

most dealers are incompetent fyi....... I'll bet its the roof.
I'd be hitting it with a power wash on every door, window and roof and call it good if it stays dry

4th gens don’t have cooling TED’s, that’s only the 3rd gens. The 4th gen relies solely on fan for ventilation. So cross that one off the list.
Doh!! It sounded good.. That's lame btw. I was wondering why these seats didn't get as cold as my 2014 Flex and 2010 F150.

2nd Gen has a TED as well, it works great I my '03. I can't imagine buying an 80k version of my truck with just a fan... You effectively have no cooling until the vehicles ambient temp drops significantly. In peak summer heat that could be awhile. I'll add that to the ever growing list of reasons I'm not a large fan of the 4th Gen. It has its fair share of good things but that other side of the list is getting longer and longer.
